Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The fingerprint identification module provided by the embodiment of the invention combines fingerprint identification and touch pressure, and has higher pressure induction sensitivity by improving the pressure detection component, and meanwhile, the packaging volume of the fingerprint identification module can be effectively reduced, and the reliability of the pressure detection component is improved. Referring to fig. 1, an embodiment of the present invention provides a fingerprint identification module, which includes a fingerprint identification module 1 and a pressure detection module 2 located at a lower layer of the fingerprint identification module 1.
Among them, for the fingerprint recognition module 1, see fig. 2 and 3, includes a fingerprint recognition sensor 1 and a flexible circuit board (FPC) 12. The flexible circuit board 12 and the fingerprint sensor 11 are packaged together by SMT (Surface Mount Technology). The flexible circuit board 12 is located on the lower layer of the fingerprint sensor 11 and is used for sending the fingerprint signal collected by the fingerprint sensor 11 to the main control module of the terminal. Specifically, in fig. 3, a device region 13 is disposed on a portion of the flexible circuit board 12 outside the key region, and is connected to a main control module of the terminal through an FPC connector 14.
The sensor 11 may be a capacitive, optical, radio frequency or other principle based sensor for fingerprint recognition. Wherein,
the principle of capacitive sensors is to integrate a semiconductor array of pixel electrodes on a substrate, such that the substrate acts as one plate of a capacitor. When the finger is attached to the substrate, the finger and the pixel electrode form one plate of a capacitor. The silicon cells and the conductive subcutaneous electrolyte form an electric field, and the capacitance values are different because the finger surface is uneven and the actual distance between the convex points and the concave points, which are in contact with the pixel electrodes, is different. Therefore, according to the fact that the capacitance value formed by the ridge and the valley of the finger fingerprint and the pixel electrode is large, the fingerprint image is obtained through processing, and the acquisition of finger fingerprint data is achieved. But the surface of the capacitive sensor is easily damaged by using silicon material, so that the service life is reduced. Further, the fingerprint image is formed by the irregularities between the valleys and ridges of the fingerprint, resulting in a low recognition rate of difficult fingers such as dirty fingers or wet fingers.
The optical sensor utilizes the refraction and reflection principle of light, the light irradiates to the prism from the bottom and is emitted out through the prism, and the refraction angle of the emitted light on the uneven lines of the fingerprint on the surface of the finger and the brightness of the reflected light are different. The optical device of CMOS or CCD will collect the picture information of different light and shade degrees, and then complete the collection of the fingerprint.
The radio frequency type sensor is divided into two types of radio wave detection and ultrasonic wave detection, the principle of the radio frequency type sensor is similar to that of sonar for detecting seabed substances, and the specific form of a fingerprint is detected by signal reflection of specific frequency. The ultrasonic waves have the capacity of penetrating through materials and generate echoes with different sizes according to different materials (when the ultrasonic waves reach the surfaces of different materials, the ultrasonic waves are absorbed, penetrated and reflected to different degrees). Therefore, the positions of the ridges and the valleys of the fingerprint can be distinguished by using the difference of the skin and the air in the sound wave impedance, and the fingerprint information is acquired.
In order to protect the detecting device in the fingerprint identification module 1 from being damaged by external force, it is preferable that a reinforcing sheet 3 is provided at a lower layer of the fingerprint identification module 1 for reinforcing the strength of the fingerprint identification module 1. Wherein, the reinforcing sheet 3 is adhered to the back of the flexible circuit board 12 by means of hot melt adhesive. The lower layer of the reinforcing sheet 3 is provided with a pressure detection module 2.
The pressure detection module 2 is located at the lower layer of the reinforcing sheet 3 and is attached to the back of the reinforcing sheet 3 through adhesives such as double-sided adhesive, foam adhesive, water glue and the like. The pressure detection module 2 is a flexible circuit board with a size slightly larger than that of the fingerprint identification module 1 to detect the touch pressure of each area of the fingerprint identification module 1. The pressure detection module 2 may be connected to the flexible circuit board 12 in the fingerprint identification module 1 by hot pressing or welding, or connected to the main control module of the terminal through the FPC connector by providing the FPC connector, for example, the flexible circuit board in fig. 3 is provided with a device area 21 (including an amplifier, an analog-to-digital converter, a micro control unit, and the like), and connected to the main control module through the FPC connector 22.
Specifically, the flexible circuit board of the pressure detection module 2 uses a flexible insulating material as a substrate, the flexible insulating substrate is printed with an ink sensing pad 23 and a copper trace (not shown), and the ink sensing pad 23 is connected with the copper trace through a gold finger (not shown). The flexible insulating substrate may be a polymer such as polyimide, Polyester (PET), Polyethylene (PE), or polyethylene naphthalate (PEN). The pressure sensitive ink block can be made of high density polyethylene (density of 0.940-0.976 g/cm)3) And graphite semiconductor composite. In addition, the surface of the flexible circuit board is covered with an electromagnetic shielding film for shielding the interference of external devices to the pressure detection module.
For the pressure sensing oil ink block 23 on the pressure detection module 2, in an embodiment of the present invention, a differential bridge arrangement form is adopted to detect a touch pressure value. Specifically, as shown in fig. 4, every 4 pieces of the inductive ink 23 constitute a differential bridge. Each bridge arm is provided with a pressure sensing oil ink block 23. One diagonal end of the differential bridge is connected with a bridge power supply, and the other diagonal end outputs a measurement voltage U for detecting a touch pressure value. When pressure acts on the fingerprint identification module 1, the fingerprint identification module 1 can elastically deform to change the resistance of the pressure sensing ink block, the small change of the resistance is converted into the change of the measuring voltage U through the differential bridge, the change is amplified into a processable signal through the amplifier of the device area 21, the processable signal is converted into a digital signal through an analog-to-digital converter and then sent into the MCU for operation processing, and the processable signal is sent to the main control module of the terminal.
Because the differential bridge has high sensitivity and small nonlinear error and has a compensation effect on same-symbol interference, the pressure-sensitive ink blocks are preferably arranged on the front surface and the back surface of the flexible insulating substrate, so that the temperature drift can be favorably inhibited. For example, in fig. 4, 8 pressure sensitive ink sticks are actually provided, and 4 pressure sensitive ink sticks are provided on each of the front and back surfaces (the back surface is not shown).
The arrangement of the pressure sensing oil ink blocks can be flexibly arranged according to pressure distribution and required sensitivity. Preferably, the pressure sensitive ink blocks are arranged in a matrix to facilitate construction of the differential bridge. The arrangement specification of the matrix is explained by taking 4 pressure-sensitive ink blocks as an example. Specifically, 4 pressure sensitive ink blocks are arranged in a rectangular shape, and the distance between the length direction (row) is 3 mm-5 mm, and the best is 4 mm. The width direction (row) interval is 1 mm-3 mm, preferably 2 mm.
In order to ensure the accuracy and the sensitivity of the bridge, the resistance value of each sensing ink block is required to have consistency, and the relative error of the resistance value is not more than 5%. Because the resistance of the pressure-sensitive ink block is related to parameters such as the resistivity, the printing area, the ink thickness and the like of the pressure-sensitive ink material, the specific resistance value needs to be matched with the impedance of a subsequent processing circuit. The number and size of the pressure sensing oil ink blocks on the pressure sensing module can be changed according to the shape of the fingerprint identification module 1 so as to meet the requirement of pressure sensitivity. Preferably, in the embodiment of FIG. 4, the printing area of the single pressure-sensitive ink can be 2-5 mm2The shape of the material can be a symmetrical shape such as a rectangle, a circle, a triangle and the like, and a square with 2mm by 2mm is preferred; the ink thickness is preferably 10nm to 30nm, more preferably 20 nm.
According to the fingerprint identification module provided by the embodiment of the invention, the pressure sensing oil ink block is used as a detection device of the pressure detection module, so that the fingerprint identification module has higher pressure sensing sensitivity, meanwhile, the structural part is slightly changed, and a mechanical structure is not involved, so that the high reliability of the pressure detection module is ensured, and meanwhile, the space occupied by the pressure sensing oil ink block is small, so that the packaging volume of the fingerprint module can be effectively reduced, and the space utilization rate of a terminal is improved.
The embodiment of the invention also provides a terminal, which is shown in fig. 5 and comprises a main control module and the fingerprint identification module; wherein,
the main control module is used for controlling the fingerprint identification module in the fingerprint identification module to collect fingerprints when the touch control pressure value detected by the pressure detection module in the fingerprint identification module is greater than a preset threshold value, matching the collected fingerprints with the preset fingerprints, and executing control operation when the matching is successful.
Specifically, as shown in fig. 6, when a finger presses the fingerprint module, the fingerprint identification module 1 slightly deforms, the resistance value of the pressure-sensitive ink on the pressure detection module 2 changes, the voltage of the balance point of the differential bridge changes accordingly, and the pressure value of the pressing degree is obtained through the processing of the amplifier, the analog-to-digital converter and the MCU in the device area 21. The master control module compares the touch control pressure value obtained by the pressure induction module 2 with a preset pressure threshold value; if the preset pressure threshold is reached, the fingerprint identification module 1 collects a fingerprint image.
Further, comparing the acquired fingerprint image with a fingerprint prestored in a fingerprint database; and if the matching is successful, acquiring the pressure level of the touch pressure, and executing different operations according to the corresponding pressure level. The specific operation type can be set by the user in the terminal. The user can also set the pressure level by himself. For example, two stages are provided: the light pressure is regarded as non-active contact, and operations such as equipment unlocking and the like are not carried out; the heavy pressure is regarded as active contact, and operations such as unlocking the device, opening a secondary menu, entering a specific application and the like can be performed. Of course, the present invention may also be divided into multiple stages corresponding to different operations, such as starting a music player and starting a camera, and the present invention is not limited specifically.
Based on the above, the terminal provided by the embodiment of the invention can not only collect the fingerprint image for identity recognition, but also perform different operations according to the magnitude of the pressure degree, such as unlocking equipment, opening a secondary menu, entering a specific application program, and the like. Therefore, the fingerprint identification module can be used in a differentiated and diversified manner, the application diversity can be increased, the application range of the intelligent terminal is widened, and abundant use experience is brought to a user.
